Part 10: Electromagnetic compatibility (EMC) requirements
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60974-10 has been prepared by IEC technical committee 26:
Electric welding.
This fourth edition cancels and replaces the third edition published in 2014 and its

4 General test requirements
4.1 Test conditions
Tests shall be carried out on completely assembled equipment representative of the series
production. Tests shall be performed within the specified operating conditions given in
IEC 60974-1:2017 and IEC 60974-1:2017/AMD1:2019 or IEC 60974-6:2015, and at the rated
supply voltage and frequency. Results obtained for RF emission and immunity at 50 Hz are
valid for the same model operating at 60 Hz and vice versa.
Where this document gives options for testing particular requirements with a choice of test
methods, compliance can be shown against any of the test methods, using the specified limits
with the restrictions provided in the relevant tables.
Identical units may be used for testing in parallel. In this case, this information shall be
recorded in the test report.
4.2 Measuring instruments
The measuring equipment shall comply with the requirements of CISPR 16-1-1:2019 and the
standards referred to in Table 6, Table 7 and Table 8 as applicable.

4.3 Artificial mains network
Measurement of the mains terminal disturbance voltage shall be made using an artificial
mains network, if commercially available, consisting of 50 Ω/50 µH or 50 Ω/50 µH + 5 Ω V-
network as specified in CISPR 16-1-2:2014 and CISPR 16-1-2:2014/AMD1:2017.
The artificial network is required to provide a defined impedance at RF across the mains
supply at the point of measurement and also to provide for isolation of the equipment under
test from ambient noise on the power lines.
4.4 Voltage probe
A voltage probe as specified in CISPR 16-1-2:2014 and CISPR 16-1-2:2014/AMD1:2017 shall
be used when the artificial mains network cannot be used. The probe is connected
sequentially between each line and the reference earth. The probe shall consist of a blocking
capacitor and a resistor such that the total resistance between the line and earth is at least
1 500 Ω. The effect on the accuracy of measurement of the capacitor or any other device
which may be used to protect the measuring receiver against dangerous currents shall be
either less than 1 dB or allowed for in calibration.
4.5 Antennas
In the frequency range from 30 MHz to 6 GHz, the antenna(s) used shall be as specified in
CISPR 16-1-4:2019.
Measurements shall be made for both horizontal and vertical polarization.
On an OATS or in a SAC, the nearest point of the antenna(s) to the ground shall be not less
than 0,25 m.
For measurements in a FAR, the antenna height is fixed at the geometrical middle height of
the validated test volume.
4.6 Coupling/decoupling network (CDN)
If a shielded chamber is required and the load is situated outside the shielded chamber, a
load-decoupling network connected to the outside load via suitable RF filters shall be used
inside the chamber. A 150 Ω CDN AF 2, as specified in IEC 61000-4-6:2013, suitable for the
respective load current and voltage, shall be used. The RF-port of the CDN shall be
terminated with 50 Ω.
Any suitable coupling devices specified in CISPR 16-1-2:2014 and CISPR 16-
1-2:2014/AMD1:2017 may be used for the conducted emission assessment of signal, control
or measurement ports.
